Developer experience

Practicing software engineering, I have been involved in designing and developing highly scalable heterogeneous systems. I have taken part in crafting high-performance applications as well as cross-platform solutions, on premise and in the cloud. My interests include insights from data, machine learning, multi-paradigm and domain-specific languages, distributed systems, automated software engineering and portable software. I have work as well as teaching experience in software architecture, data pipelines, web technologies, functional and logic programming. Besides being affiliated with companies including IBM, LogMeIn, Ericsson and Nokia, I have run various open-source projects. I have team leadership experience in an agile context, and enjoy speaking and writing on technical subjects. Having a diverse background, with both academic and computer software industry experience, I am able to apply my previous knowledge to solving new and complex problems.

Open-source contributions

Besides being affiliated with for-profit companies, I have run various open-source projects. Check out the complete list of repositories on GitHub and BitBucket. Some of my open-source projects are showcased below.

sigplus

sigplus adds photo and multimedia galleries to a Joomla article with a simple syntax. It takes a matter of minutes to set up but comes with a vast range of options for advanced users.

Despite its versatility, sigplus is completely free. It is a full-fledged product with all features included, there is no need to buy a commercial professional version for extra features or purchase club membership to unlock additional privileges. Since its publication in the Joomla Extensions Directory in March 2010, sigplus has been rated the best extension in the Photo gallery category. Needless to say, if you find sigplus useful, we appreciate a donation.

frugally-deep

frugally-deep is a small header-only library written in modern and pure C++ to run the prediction (forward pass) of a neural network model trained with Keras and Python but without linking your application against the TensorFlow library. It re-implements a (small) subset of TensorFlow, i.e. the operations needed to support prediction, leading to a much smaller binary size than linking against TensorFlow.

I have contributed to the implementation of several layer types including Conv1D, GRU, CuDNNGRU, LSTM, CuDNNLSTM and Embedding as part of our efforts with IBM Watson Media.

Joomla extensions

Products released as part of these projects have been top-ranked by their user community, including several Joomla extensions:
